VIDEO RECEIVER EDP 70568 - D This Video receiver is equipped with a trafo isolated video input for both Symmetrical video, over Twisted pair wires, or Asymmetrical video, using coax cables. The Receiver can compensate signal loss in long distance wires.
FEATURES - Connector boards and accessories enable mounting on Mounting rails, Euro racks 4TE, Circuit breaker boxes 1 division or straight on a wall. - Indication and adjustments in front. - Connection through a 15pin D-sub. - Power polarity through a diode. - ESD protection by a ferrite barrier. - Passive and galvanic isolated input. - Signal clamp for fixed black level. - Sync and signal detection outputs. - Distributed Asymmetric outputs.
TECHNICAL DATA 0,6-1,2Vpp into 124R 0,7-1,3Vpp into 75R Video trafo, 1KV Open collector in serial with 10R, max. 80mA Error disable: Diode collector, disable is 0,3 to GND Sync output: 1Vpp 75R termination sync offset is GND Amplifier: 10MHz bandwidth +30 db at 3 to 6MHz Adjustable to 1Vpp
